My wife and I are doing an extended trip across much of the US. There are three devices on the dash: action cam, phone and GPS. Right now the GPS is a Garmin 660. It has its own power cable and there's no easy way to hack that. So there are three cables running across the dash. What I want to do is have only one cable across the dash. I can use a USB splitter to combine the phone and action cam cables . The Garmin demands its own wire. I'm stuck with two cables.
AFAIK, the car mount comes with a USB cable connector. Good news so far. However it seems that the TT docs say the 550 needs its own USB source that must be able to handle the current demanded to keep the battery from discharging. The car mount comes with a car plug in adapter which is supposed to be able to keep the 550. There's no mention about whether the "magical" TT adapter does something special or one of the TT USB ports is a 2.1A port.
Phrased differently, how much current does the Rider 550 need?

Your device should have 1.2Amps to run AND charge the battery.
The charger must be rated at 5V 2amps as the device draws 1.2amps
To check that your charger is working get a USB meter for $7.99 from Amazon
